Acoustics and Vibrations

Environmental noise measurement: noise and vibrations measurement

Environment measurement has the objective of monitoring noise and vibrations generated by activities, facilities, behaviors, equipments, works and services, both in exterior and interior spaces.

The purpose of this control is the verification in situ of compliance with the different existing regulations on noise pollution, both municipal and, in this case, autonomous, national or European, that expect to prevent the exceedance of limit values of noise and/or vibrations level transmission produced by activities, facilities, behaviors, equipments, works and services and evaluated individually depending on the use of the area or of the establishment and on the time slot. These levels are called Maximum Allowable Noise Levels.

Services we offer regarding environmental measurement are:

Testing: Measurement and evaluation of environmental noise produced by activities, facilities, works and services.

In exterior spaces: both the receiver and the source are outside.

In interior spaces, transmitted by air: the receiver is inside and the source is outside.

In interior spaces, transmitted by the structure: both the receiver and the source are inside.

Insulation measurements in buildings: airborne noise and impact noise

Objective of sound insulation

To prevent the transmission of noise generated in an area to adjacent ones. As well as we expected to prevent the transmission of outsider noise to an interior area, in order to provide the occupants of buildings an appropriate protection against noise. Insulation includes, depending on the type of noise we want to isolate, protection against airborne noise and impact noise.

What advantages can acoustic control provide in the building?

Check the acoustic insulation in situ of concrete parameters in order to comply with current legislation on noise.

The acoustic testing allows a progressive adaptation and preparation facing the needs imposed by legislation.

Meet the growing demand of the house final user.

Get a strong selling point, a competitive advantage in the sector.

Measurements of noise in the workplace

There are many reasons for measuring noise in the workplace. The most important is to determine if noise levels are high enough to produce hearing risks in people exposed, that is the verification in situ of compliance with legal regulations on prevention of occupational risks.

Royal Decree 286/2006 deals with the protection of workers against the risks from exposure to noise at work, and particularly for hearing. Exposure to noise of workers is assessed in order to determine if it exceed the fixed limits. There are situations where the noise level is not significant enough to cause hearing damage, but it causes interference with oral communication. It is important to keep in mind that the combined noise levels of several machines may exceed the desired noise level in one area, although levels of individual machines are acceptable.

Services we offer regarding measuring in industry are:

Testing: Measurement of noise for workers protection.

Regulations: Royal Decree 286/2006, 10 March, on workers’ health protection and safety against risks related to exposure to noise (BOE No.60, of 11/03/06).

As established in Article 33 of Law 7/2002, 3 December, of the Generalitat Valenciana, and in municipal regulation of local bodies, the different elements of the building and its facilities must meet certain conditions of acoustic insulation.

To get the license occupancy buildings, in addition to certificates fixed by current regulations, it is required the acoustic insulation certificates, carried out under standard conditions, of the elements that constitute the vertical enclosures of the façade and of the attached building walls, the horizontal enclosure (forged with the first floor) and the separating elements of rooms containing sources of noise (elevators, boilers…).
